Nourrir les oiseaux en été : oui, mais attention aux maladies

In winter, supplementary food is often the only option for birds as natural food sources get buried under snow and ice and insects and fruits are few and far between. But in summer bird feeding can be useful as many are busy raising their young. Some aliments are particularly recommended such as crumbled up cake, plain biscuits, sunflower , mealworms or fruits.
The main caution around summer bird feeding is the concern for cleaning feeders often enough to prevent diseases to spread. For instance, during the month of August 2011, avian pox is spreading among garden birds in Great Britain, with Great Tits particularly badly hit by the lesions it causes.
